PROCESS OF FORMING POlINTED BLAH KS FOR BELT-HOOKS FROM A METALLICSTRAND.

Specification of Letters Patent.

Patented May 4, 1915.

Application filed June 11, 1914. Serial No. 844,441.

To all whom it may concern:

Be it known that I, DAVID T. GRAHAM, a

citizen of the United States, residing at St. Louis, in the State ofMissouri, have mvented certain new and useful Improvements in Processesof Forming Pointed Blanks for Belt'Hooks .fnom. a Metallic Strand and Ido hereby declare the following to be a full, clear, and exact descrition of the invention, such as will enable otliers skilled in the art towhich it appertains to make and use the same.

My invention relates to the process of making pointed blanks for belthooks, to conveniently, neatly and permanently hook the ends of belts.

One of the objects of my invention is the process of making a pluralityof points from a single strand of metal.

Another object of my invention is to first swage the metal and then cutthe swaged portion of the metal to form a plurality of independentpoints in such manner that a minimum amount of metal is wasted.

Still another object of my invention is to cut a plurality of points outof a single strand of metal by first swaging and then cutting the swagedmetal in such manner that not only a minimum amount of metal is wasted,but, if desired, all four sides of the point formed by my process aresloped to an approximate point. And still another obyect of my inventionis to cut a plurality of points from a single strand of metal, saidmetal being swaged at predetermined dlstances to form two sloping sidesthat are oppositely disposed by cutting said swaged metal so as to formsloping sldes, oppositely disposed, that are at right angles to thefirst mentioned sloping sides.

These and other objects in view are to be developed as the specificationproceeds wherein a preferred embodiment of the process is shown in thedrawings as illustrating one means of accomplishing this processwithinthe scope of the claims appended hereto.

I shall proceed to describe my process wherein similar characters ofreference refer to similar results as can be seen in the drawings, inwhich,

Figure 1, is one of the independent hooks derived from my process asejected from the machine that forms a construction of the same. Fig. 2,is a view of a metallic strand having swaged portions thereto, to formtwo of the sloping sides that are oppositely disposed in the points thatgo to make up my point. Fig. 3, an edge view of a metallic strandlooking at right angles to that shown in Fig. 2. Fig. 4, adiagrammatical view showing the cuts in said swaged portions that go tomake up the sloping sides that are oppositely disposed and which set atright angles to the sloping sides formed by swaging. And Fig. 5, is aview showing the metallic strand having its point swaged and cut to formthe independent points that go to make up, say for instance, independenthooks.

In Fi 1 of the drawings, is shown one of my hoo 5 in its finished stateas ejected from the machine that makes belt hooks by my process, saidhook 5 containing the body portlon 8 and the end portions 6 and 7, saidend portions having 4 sloping sides thereto, each two of which beingoppositely disposed and said oppositely disposed sides being at rightangles to each other as at 9 and 10 and 11 and 12 of theFig. 1. Theseindependent hooks are made from a single strand of approximately flatmetal 13, which at predetermined distances is swaged as at 14 and 15 ofFig. 2, these swages taking place on opposite sides of the metal so asto cut oppositely disposed sloping sides 11 and 11' and 9 and 9'. Thevery act of swaging this metallic strand 13 as above described pushesthe metal outward thereby lengthening the metallic strand 13 andattenuating thinning out and stretching the metal so swaged. We nexttake and out said swaged surfaces by two oppositely disposed andapproximately right angular cuts 16 and 17, said cuts beingdiagrammatically set forth in Fig. 4 of the drawings, so that when saidcuts are made, two sloping, and oppositely disposed sides 18 and 19 arehad, these oppositely disposed sides being at right angles to the sides9 and 11 as previously pointed out in the description illustrated byFig. 1. By this arrangement a certain portion of a metallic strand suchas number 20 shown in Fig. 5 ofthe drawings is wasted, but this wasteportion is that part of the metallic strand 13 which receives theheaviest swaging, and owing to the fact that the metal has been thinneddown at this point, it is readily obvious that only a minimum amount ofmetal is wasted in this respect being a decided im rovement in processesforming belt hooks 0 like character.

If desired only three sides of a metallic strand can be operated upon bymy process to derive a point. This can be achieved by swaging a metallicstrand, having three rounded sides and one flat side, on the flatsideand cutting two of the rounded sides which are oppositely disposedand at right angles to the flat swaged side. In this case the point willhave three sloping sides and one straight side.

I have now described my process and independent hook' derived thereby,and what I claim as new and desire to secure by Letters Patent, is,
